304 vs 316 Stainless Steel Wire Mesh: Which Grade Fits the Job?

304 is the common industrial baseline

304 stainless mesh is widely used for screening, guards, and general filtration where chloride exposure is limited. It usually gives a good balance of price, availability, and corrosion resistance for standard industrial use.

316 handles harsher media and environments

316 adds molybdenum, which improves resistance in marine air, salt-bearing environments, and more aggressive chemical applications. Buyers often move to 316 when service life matters more than initial material cost.

Choose by environment, not habit

• Use 304 for general indoor or mild industrial conditions.
• Use 316 for chlorides, marine exposure, and stricter corrosion demands.
• Confirm whether the extra cost changes product life enough to justify the upgrade.

The right grade is the one that matches the operating condition, cleaning method, and expected service interval.
